IMPROVEMENT IN COMPOSITIONS FOR BUILDING PURPOSES.

Specification forming part of Letters Patent N0. 1 64,850, dated June22, 1875: application filed June 17, 1875.

To all whom it may concern Be it known that 1, ARZA T. LYCN, ofCincinnati, in the county of Hamilton and State of Ohio, have inventedcertain new and useful Improvements in Composition for BuildingPurposes, of which the following is a specification This inventionrelates to a new and improved composition of matter for buildingpurposes, being designed particularly for the manufacture of artificialbuilding-blocks, as a substitute for natural stone; also as a substitutefor the ordinary mortarfor {)IlSIZQEIllgjVttIIS, and for theconstruction of water'and fire proof floors and partitions for houses,and a variety of other similar purposes.

The invention consists in a compound composed of asbestu hydrauliccement, coal-ash- .es, lime, and sulphate iff'lnpe, orpIElsteg-ofparfsfinixed with water to bring it to the consis ency ofmortar; the mass, after being properl y molded or spread and properly dred, being saturated with silicate of soda, or water-glass, as more lully hereinafter set forth.

In preparing the improved compound, the ingredients are prepared andmixed in the following proportions, viz: coarsely-ground asbestustwenty-two pp u gls; Portland or other 1i'v d ra u lie cement twenty-twopounds; coaI- as ies wen ywo poT1Ti'd's;"ai1'-slal ed Inne' twenty-twopounds; and calcined suI iIIate oI lime, or plaster-ot-paris, thirtypounds.

Iese 1n gret Ien s ar mix'ed'linil'thorou ghl y incorporated withsufficient water to bring the mass to the consistency of omy plasterersmortar, in which coriditi'on the compound is ready to be molded orapplied to walls, ceilin gs, or floors, in the same manner as ordinaryplaster or concrete, or to be formed into building-blocks in suitablemolds. In either case,

after application, or after being formed into blocks, the compound isleft to dry for about one Week, when it is saturated with solublesilicateof soda or potaslijh'omnronly knownas' waterlass, after which itis again allowed to my? w I In the manufacture of building-blocks, themass, as above prepared, is molded in suitable forms, and allowed to dryfor about one week. The blocks thus formed are then immersed in a bathof the soluble silicate of soda or potash, for about five days, or untilthoron ghl y saturated, after which they are removed and dried, whenthey are ready for use.

When the compound is to be applied to ceilings, walls, or floors, it isspread thereon in the manner well known to plasterers or manufacturersof concrete pavements, and, after properly setting or drying, is washedor floated with the soluble silicate, until thoroughly saturated withthe same, after which it is allowed to dry, eventually becoming as hardas stone.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

The composition of matter for building purposes, consistingot' asbestos,hydraulic cement, coal-ashes, air-slakttrnfitianupnsmgpgg, about in theproportions spe'cifieilfand thoroughly mixed and incorporated Ivithwater, and molded or applied as specitIed, and saturated with solublesilicate of soda. or potash, substantially as described.

In testimony that I claim the foregoing, I have hereunto set my hand inthe presence of the subscribing witnesses.
